New BD Icon, what purpose for blue and green lights

Played with the new BD Icon headlamp the other day.  Curious what purpose the blue and green LED flood lights serve?  I use the red light all the time but a bit confused on why I would want the blue and green.  

Red provides better contrast(more details) up close  doesn't mess with night vision hard to see/distinguish from far away

Green provides softer contrast than red, plus animal/fish aren't distracted by it and insects aren't attracted to it

Blue shows blood or bodily fluid better, and possibly scopions( it may have to be true uv for this) also good for paper maps

If they are using regular royal blue LEDs (450-465nm), they should glow pretty well. They certainly make corals and all kinds of other fluorescent marine animals glow.
